Description

  The present invention relates to a post-foaming hair dye composition.

  As shown in Patent Document 1, a hair dye composition containing an HC (hair color) dye and a basic dye is known. This type of hair dye composition is generally called a color treatment or the like, and is used for hair coloring (particularly white hair) along with hair conditioning.

  The hair dye composition dyes hair by adhering pigments such as HC dyes to the surface layer of the hair. It can be said that it does not follow. However, the hair dye composition has been widely used in recent years because it has little damage to hair and skin, and is one-pack type and easy to handle.

  In addition, as the dosage form of the said hair dye composition, as shown in patent document 1 etc., things, such as cream form and foam form, are known.

  For example, in the case of a creamy hair dye composition, the adhesion to the hair is relatively good, but depending on the amount used, it may gradually drip from the hair over time. In particular, when a cream-like hair dye composition is applied to wet hair, it has been a problem that it tends to sag from the hair.

  In addition, the water-based foam-like (foam-like) hair dyeing composition has a rough foam quality, and the foam collapses to easily return to a liquid state. For this reason, when applied to hair, the hair dye composition is liable to dripping, so that it is difficult to sufficiently attach the hair dye composition to the hair. In some cases, it was difficult to demonstrate.

  It is also conceivable to prevent dripping from the hair by reducing the amount of the hair dye composition used. However, when the amount used is small, it is difficult to spread the hair dye composition evenly over the entire hair, and the hair cannot be dyed evenly.

  As described above, the conventional hair dye composition easily hangs down from the hair, and it is difficult to sufficiently spread the hair evenly with a small amount.

The present invention has been completed.

Means for solving the above problems are as follows. That is,
<1> 0.2-1.2% by mass of HC dye and / or basic dye, 1.0-7.0% by mass of cationic surfactant, 0.5-3.0% by mass of nonionic surfactant %, 3.0 to 10.0% by mass of higher alcohol, 50 to 97% by mass of water, and 1.0 to 7.0% by mass of a post-foaming agent.

(Method for producing post-foaming hair dye composition)
The post-foaming hair dye composition is manufactured by adding the post-propellant to the pre-dyeing composition composed of components other than the post-propellant among all the components constituting the post-foaming hair dye composition. The A precursor hair composition is manufactured by mix | blending each component suitably using a well-known method. However, in the case of the present invention, the viscosity of the precursor hair dye composition (that is, the state in which the post-foaming agent is removed from the post-foaming type hair dye composition) is adjusted to a range of 3,000 to 10,000 Pa · s. There is a need. When the viscosity of the precursor hair dye composition (in the state where the post-foaming agent is removed from the post-foaming hair dye composition) is in such a range, the post-foaming property of the post-foaming hair dye composition is obtained.

(container)

There is no limit. As a container used for the post-foaming hair dye composition, the propellant is housed in the housing portion together with the post-foaming hair dye composition, and the actuator is operated by pressing (pushing) a button to An aerosol container (so-called spray can) that is discharged to the outside is preferable.

  In particular, as an aerosol container for housing the post-foaming hair dye composition, a dedicated inner bag (for example, pouch) for housing the post-foaming hair dye composition in the housing section (for example, a can-shaped housing section). A double structure type aerosol container having a bag) and separating and storing the post-foaming hair dye composition and the propellant is preferable. If it is a double structure type aerosol container, the post-foaming type hair dye composition is housed in an inner bag, so that it can be stored for a long time.

  In addition, there is no restriction | limiting in particular as a propellant used for an aerosol container, A well-known thing (for example, nitrogen gas, LPG gas, etc.) is used.

(After foaming)
In the state where the post-foaming hair dye composition of the present invention is stored in a predetermined container (for example, an aerosol container), foaming is suppressed, and after the liquid is discharged from the container, the temperature condition and the like are changed. Thus, the post-foaming agent gradually evaporates and the post-foaming hair dye composition gradually foams.

  The foamability of the post-foaming hair dye composition is adjusted so that, for example, the volume is about 3 to 5 times that immediately after being taken out of the container. However, the degree of foaming of the post-foaming hair dye composition is not limited to this, and is appropriately set according to the purpose.

(Other characteristics)
In addition, the post-foaming hair dye composition of the present invention becomes a stable foam after post-foaming and has excellent foam persistence. Therefore, the post-foaming hair dye composition of the present invention can be distributed evenly to the hair, and as a result, the hair can be uniformly dyed without unevenness.

  In particular, the post-foaming hair dye composition of the present invention can adhere to wet hair in a foamed state for a long time without dripping.

The results are shown in Table 1.

〔Evaluation test〕
About the hair dye composition of each Example and each comparative example, the evaluation tests 1-5 shown below were done. The results of each evaluation test are shown in Table 1. In each evaluation test, the hair dye composition was housed in a double-structure push-type aerosol container and discharged (hair dye composition) from the aerosol container. Nitrogen gas was used as the propellant filled in the aerosol container.

(Evaluation test 1: Evaluation of post-foamability)
A small amount of the hair dye composition (about 5 g) was discharged from the aerosol container onto the palm, and the foamed state after leaving for 3 minutes was visually evaluated. The evaluation test was performed in a room temperature (25 ° C.) environment. The temperature of the palm of the examiner was about 32 ° C. The evaluation of the foamed state was in accordance with the criteria shown below.

<Evaluation criteria>
A: Slowly foamed after being discharged to the palm, and foamed 4-5 times after 3 minutes. After foaming, the foam was gradually foamed and foamed about twice after 3 minutes. X: foamed immediately after being ejected to the palm, or almost foamed

(Evaluation test 2: Evaluation of foam persistence)
A hair dye composition (about 10 g) discharged from an aerosol container is uniformly applied to the hair tip side of a wig (human hair, about 40 cm) attached to a mannequin (head), and left in that state, The foam durability of the hair dye composition was visually evaluated. The evaluation test was performed in a room temperature (25 ° C.) environment. The evaluation criteria of foam persistence were according to the criteria shown below.

(Evaluation test 3: Evaluation of hair dyeing power)
Each hair dye composition (about 1 g) discharged from an aerosol container was applied to a bundle (test hair bundle) of about 2 g of white hair bundles of yak, and then allowed to stand at 25 ° C. for 20 minutes. Thereafter, the test hair bundle was washed with water and dried. About the test hair bundle after drying, based on the reference | standard shown below, the hair dyeing power was evaluated.

<Evaluation criteria>
A: Hair is firmly and evenly dyed.
○: Hair is dyed firmly, but the uniformity is weak △: Hair dyeing power and uniformity are weak ×: Almost not dyed

(Evaluation Test 4: Evaluation of Treatment Effect)
Twenty men and women were panelists, and the hair dye composition discharged from the aerosol container by each paneler was applied to the entire hair after being washed, and left for 20 minutes. Thereafter, the hair was rinsed with warm water and dried, and each panelist evaluated the treatment effect (quality of moisturizing feeling, etc.) of each hair dye composition. The evaluation criteria are as follows.

<Evaluation criteria>
◎: When 16 or more people are judged as good ○: When 11-15 people are judged good △: When 6-10 people are judged good ×: When five or less people are judged good

◎: When 16 or more people are judged as good ○: When 11-15 people are judged good △: When 6-10 people are judged good ×: When five or less people are judged good

  The unit of each numerical value shown in Table 1 represents “mass%” unless otherwise specified. As shown in Table 1, the post-foaming hair dye compositions of Examples 1 to 5 using a cationic surfactant and a nonionic surfactant in combination are post-foaming properties, foam persistence, hair dyeing properties, and treatment effects. And it was confirmed that it was excellent in usability. In particular, the post-foaming hair dye compositions of Examples 1 to 3 in which the amount of lauramine oxide used as the nonionic surfactant is larger than those in Examples 4 and 5 are post-foaming, foam persistence, and hair dyeing properties. It was confirmed that the treatment effect and usability were excellent.

  On the other hand, the hair dye composition of Comparative Example 1 containing no nonionic surfactant resulted in foaming immediately after being discharged from the aerosol container.

  Moreover, although the post-foaming property was obtained in the hair dye composition of Comparative Example 2 that did not contain a cationic surfactant, there were problems in foam sustainability, usability, and the like.

  Moreover, the hair dye composition of the comparative example 3 has many compounding ratios of the post-foaming agent compared with the Example. As a result, when the post-foaming agent was added to the hair dye composition (precursor dye composition), the composition was separated. Therefore, for Comparative Example 3, each evaluation test could not be performed.

  The hair dye composition of Comparative Example 4 hardly foamed (post-foamed), resulting in poor foam sustainability and usability.

  The hair dye composition of Comparative Example 5 was foamed immediately after being discharged from the aerosol container. In addition, the foam persistence and usability were also poor.
